Y315-4电机轴承温度影响因素的试验和分析

Test and Analysis on the Temperature-influence-factor of Bearings Installed on the Y315-4 Motor

出于对设备运行安全的关心,用户越来越关注电机轴承的温度。通过试验数据分析,提出机壳通风槽的有无、内外部通风的设计等对绕组温度和轴承温度的影响程度,对电机的设计有指导意义。

In order to guarantee the safe operation of the equipment, more and more customers pay serious attention to the temperature of the motors＇ bearings. Based upon the testing data, the difference of influence degree to the temperature of windings and bearing between ones furnished with or without ventilating slots and inner ＆ outer ventilation in the enclosure was discussed. It is of great guidance function while designing motor.
